Q

What ramus is continuously forward to supply the muscles and skin anterolaterally to the body wall and all the muscles and skin of the limbs

Study These Flashcards
A

Anterior ramus

25
A fusiform swellings on the posterior root of each spinal nerve just proximal to the root's junction with a corresponding anterior root?
Sensory ganglia
26
Irregular shaped swelling found in the paravertebral sympathetic chains, around the roots of the great visceral arteries in tge abdomen, and close to or embedded to the walls of various viscera
Autonomic ganglia
27
Dermatome for umbilical cord
T10
28
Dermatome for nipple area?
T4
29
How many pairs of spinal nerves and their ganglia?
31 pairs
30
What is the parasympathetic nucleus of the occulomotor nerve?
Edinger-westphal nucleus
31
Location of the cell bodies of the preganglionic neuron in the ANS?
Lateral gray column of the spinal cord
32
It's function is to prepare the body for emergencies.
Sympathetic
33
Effect of synpathetic?
Arterioles of the skeletal muscles are dilated
34
Effect of parasympathetic?
Heart rate decreased
35
Neurotransmitter used by PREganglionic fibers for sympathetic neurons in the lateral gray columns of the spinal cord?
Acetylcholine
36
The myelinated axons of these cells leave the cord in the anterior nerve roots and pass via this area to the paraventebral ganglia of tge sympathetic trunk?
White rami communicantes
37
This postganglionic, NONMYELINATED acons leave the paravertebral ganglion and pass to the thoracic spinal nerves as what?
Gray rami communicantes
38
These medullary cells, which may be regarded as modified sympathetic Excitor nEurons, are responsible for the secretion of these neurotransmitter.
Epinephrine. (3 E)
39
The sympathetic trunks are two ganglionated nerve trunks that extend the whole lenght of the vertebral column. Below, the two trunks terminate by joining together by a single ganglion.
Ganglion impar
40
A myelinated efferent fibers of tge craniosacral outflow are preganglionic, and synapse in peripheral ganglia located close to the viscera they innervate. The neurotransmitter is?
Acetylcholine
41
Cranial nerves that is part of the cranial sacral outflow.
Oculomotor
42
Cranial nerve that is part of parasympathetic nervous system?
Faciao
43
CN that is part of parasympathetic nervous system
Facial
44
CN part of PNS?
Vagus
45
These cells is found in tge autonomic ganglia exhibit catecholamine flourescence. In some ganglia, these interneuorons receive preganglionic cholinergic fibers, and may modulate ganglionic transmission. In other ganglia, they receive collateral branches and may serve some integrative function. And, many SIF cells contain this. What transmitter is this?
Dopamine
46
Synaptic transmitter that excites the post ganglionic neurons in both sympathetic and parasympathetic.
Acetylcholine
47
It is a nicotinic and muscarinic receptors bind to this neurotransmitter.
Acetylcholine
48
Parasympathetic pistganglionic nerve endings liberate this tyoe of neurotransmitter as tgeir transmitter substance.
Acetylcholine.
49
Parasympathetic pistganglionic nerve endings are called as what as their substance being utilized?
Cholinergic
50
Most sympathetic ganglion nerve endings liberate what as their transmitter substance?
Norepinephrine
51
Phenyleohrine is a pure simulator of these receptors?
Alpha receptor
52
Norepinephrine has greater effect of what type of receptor?
Alpha receptors
53
Bronchodilator drug albuterol mainly acts on what receptor?
Beta 2 receptors
54
These receptors are found in the lungs
Beta 2 receptors
55
Myelination is caused by
Schwann cells
56
Are glial cells that form the myelin sheath on axons outside the brain?
Schwann cells
57
specialized regions in the axonal membrane that are not insulated by myelin.
Nodes of ranvier
58
Glial cells that forms PNS
Schwann cells.
